Sorry, you missed my intent on that one, which was to have the spec clarify
that the variable bindings and function library should be considered as part
of the context, without necessarily specifying how they get updated. That
would suggest to others [but not require that the W3C specify], XPointer
parts such as I mentioned.
Motivation for the comment was that I plan on having a number of canned
XPath queries, where parts of the query are supplied by variables stored in
the execution context, and I'd like to see the spec at least nod in the
direction that XPath implementations have already headed.
BTW, where are we on the XPath scheme NOTE? I know you've been busy.

Subject: Re: Comments on XPTR Framework
Thank you for your comments on the XPointer Framework Last Call draft,
which are archived at:
http://lists.w3.org/Archives/Public/www-xml-linking-comments/2002JulSep/
0060.html
The XML Linking Working Group has collected all the comments
on the documents and decided what changes to make to the draft.
The dispositions of your comments are given below. Please reply
to www-xml-linking-comments@w3.org within one week if you wish
to make a formal objection to these decisions.
[paraphrase of request:] add pointer parts for binding variables
and extension function libraries in XPointers.
The group decided for the spec to remain silent on this, thus not
prohibiting scheme developers from adding new material (not limited
to variable bindings and function libraries) to
the evaluation context. Such developers can't rely on all
implementations
supporting it, of course, but that is always the case when adding
a new capability. Implementations that don't understand a new
pointer part will skip it, thus not adding or using the extra stuff
in the context. Implementations that do understand the schemes will
have an evaluation context with whatever additional content is needed
to support the schemes.
Best regards,
Ron Daniel Jr.
